Combination of bendamustine (B) and rituximab (R) has been associated with opportunistic infections (OI) in case reports. This retrospective analysis evaluated the incidence, risk factors, and types of infectious complications (IC) in adults with CD20+ non-Hodgkin lymphoma who received ≥2 cycles of B and either R or ofatumumab. Infection data were collected up to 1-year post-B-based treatment. Potential risk factors for IC were assessed using univariate analysis with Fisher's exact test. Four-hundred and sixteen patients were included. Incidence of IC and OI was 20 and 6%, respectively. Viral ( = 19), fungal ( = 1), and pneumonia ( = 5) infections occurred. OI was associated with lack of antimicrobial prophylaxis analysis ( = .048). The incidences of IC and OI with B and anti-CD20 antibody combination at our institution appear lower than those previously reported, possibly due to antimicrobial prophylaxis and G-CSF use.

Annual epidemics of influenza result in 3-5 million cases of severe illness and more than 600 000 deaths. Severe forms of influenza are usually characterized by vascular endothelial cells damage. Thus, influenza A viruses, including subtypes A(H1N1)pdm09, A(H3N2), as well as highly pathogenic avian influenza viruses, can infect the vascular endothelium, leading to activation and subsequent dysfunction of these cells.

Protothecosis is a severe, emerging opportunistic infection caused by the saprophytic, achlorophyllous microalgae of the genus Prototheca. Though uncommon, human and animal cases are increasing worldwide, making awareness of this fungal-like pathogen important in both human and veterinary medicine. We report a fatal case of disseminated protothecosis caused by P.

Donor cell leukemia (DCL), in which malignancy evolves from donor's stem cells, is an infrequent complication of allogeneic hematopoietic stem cell transplantation. Acute promyelocytic leukemia (APL) derived from donor cell is extremely rare and only four cases have been reported to date. Herein we report a case of donor cell-derived APL developing 32 months after haploidentical peripheral blood stem cell transplantation using posttransplant cyclophosphamide for myelodysplastic syndromes.

CAR-T therapy (chimeric antigen receptor T-cell) has revolutionized the prognosis of patients with diffuse large B-cell lymphoma (DLBCL) that have relapsed or are refractory to conventional chemotherapies. In particular, patients who have relapsed or are refractory to two lines of therapy are patients who have a poor prognosis. The advent of CAR-T immunotherapy is an innovative approach with which we can give hope of recovery even in the case of refractory disease, even for patients who are not candidates for high-dose therapies, for example due to age.

Introduction: Temporomandibular joint ankylosis is defined as permanent jaw constriction with an interincisal mouth opening of less than 30 mm, due to bony, fibro-osseous or fibrous fusion. Ankylosis may be uni- or bilateral. The complications of this ankylosis affect the functions of mastication, swallowing and phonation, sometimes facial morphology, and disturb dental hygiene.
